Pyrolysis system with eductor condenser for cooling pyrolysis gases
A recently granted patent (Publication Number: US11981866B2) discloses a system for the pyrolysis of a pyrolysis feedstock, featuring a pyrolysis reactor and an eductor condenser unit. The system includes an eductor assembly with a venturi restriction for combining pressurized coolant fluid and pyrolysis gases, a mixing chamber for condensing pyrolysis gases, and an upstream condenser unit with a clearing assembly to remove pyrolysis oil and solids buildup. Additionally, a pressure sensor is integrated to monitor pressure differences and automate the clearing assembly when necessary. The system is designed for efficient pyrolysis of biomass feedstock, with a separating unit to segregate condensed pyrolysis gases, coolant fluid, and non-condensable gases.
The system further comprises a mixing unit with stationary mixing elements, a condenser inlet clearing assembly utilizing liquid or gas jets, and a plunger or piston mechanism to clear accumulated materials in the upstream condenser unit. The upstream condenser unit is a direct contact condenser, enhancing the efficiency of the pyrolysis process. By incorporating automated features like the pressure sensor and clearing assembly, the system ensures optimal performance and maintenance, making it a promising solution for biomass pyrolysis applications. The separating unit facilitates the segregation of different components, streamlining the overall pyrolysis process and enhancing the system's effectiveness in producing pyrolysis products from various feedstocks.
